Hi there, joseph23.
Thank you for coming back here to the QuickBooks Community. I appreciate you for providing detailed information so I can share accurate details.
For users to send receipts and bills, they need to be a standard user with vendors' permissions. That said, it could be that the email addresses you're trying to enter are not for the users in QuickBooks Online. I suggest going to the Manage user section and double-check if the emails are already there. If not, you can add the owners of the email as the standard user so you're able to add them for forwarding receipts.
Here's how:
- Sign in to QuickBooks with a user profile as Master admin that has permission to manage users.
- Select the Gear ⚙ icon. Then, choose Manage users.
- Click the Edit link to check each email address.
- If you can't locate the email address, click the Add user.
- Select a user type. Then select Next. Note: Some roles count toward your user limit.
- Select the access rights for the user. Then select Next.
- Enter the user’s name and email address. Then, hit Save.
For additional information, you can refer to this article: Add and manage users in QuickBooks Online.
Once done, go back to the Receipts page and try to add the email addresses. To see additional details, you can click this article: Email receipts and bills to QuickBooks Online.
Please open this article to view steps on how you can review, edit, and match those uploaded or sent images of receipts and bills to any existing transactions to avoid duplicates: Capture and categorize expense receipts and bills in QuickBooks Online.
Please let me know if you have more questions about emailing receipts or anything else related to QuickBooks. I'm around in the Community to help you. Take care and stay safe always.
